To all whom it may concern:

Be it known that I, BENJIMAN R. LEE, a citizen of the United States, residing at Chatta noo' a, in the county of Hamilton and State of .ennessee, have invented certain new and useful Improvmnents in Demountable Rims, of which the following is a specification.

This invention relaies to an improvement in demountnble rims such as are used for mounting pneumatic time upon automobile wheels and the like, and it is u pur pose of my invention to provide a rim structure which is not only split, as is custon'mry,

but which is made up in two sections hingedly connected together and thus so arranged that a tire casing can be fitted in place upon and removed from the rim, with grenter facility.

A further object resides in constructing :1 rim expending and connecting means Whir: will force the rim sections into the proper poeition with. respect to the casing, and will rigidly connect the loose ends of the ".1111 to present the same substantially a a continuous ring.

Yet another obiect lies in .ir(.:\'iriing means by which the rim is held upon a who i, and which means is constructed that it can he expeditiously adjusted for secui'eme'nt or re lense oi" the rim.

With the above and other objects in View, whinh will he in part described and in gartunderstood from the specification, drawings, and claim, my invention consists; in certain. novel features of conen'uction and combination of parts which will he heieineitei more fully set faith.

In the drewings:

Fi ure 1 is a view in elevation showing the rim structure fitted. in place on -i folly.

Fig. 2 is a sectional view to show the mew nor of forming the rim structure and the means for fastening the ends.

Fi 4- is a fragmentary lwationel view showing the arrangement m" the parts of the fastening when Viewed from that side on which the tire is fitted, and

Fig. 5 is a fi'zignn-nim'g. sectional view to better show the looking or fastening inmum The rim comprises the too sections 1 and 2, which are hinged together at 3-, the meanber- 2, which compriew. fillllmillitlillly one third of the total extent of the ring, lining thus so mounted that it will swin within the member 1. With the parts hingedly mounted in the manner as set forth, when the member 2 is swun to have its free end embraced within the lines of the member 1 the rim structure as an entirety can be lifted from a casing to which it has been fitted and on the other hand, when the section 2 is swung out to complete the circular lines or the rim and to have the free end thereabutting against the free end. of the member 1, the rim sections will be held in this position by the binding force exerted by the casing, however, it is desirablethat some means be provided for positively locking and securing the abutting ends of themembers 1 11111152 together, and to act to force the same intophiee as well as release the end.

With thls'purpose in view, the body por- 4 tion of the member 1 is cut away at the free end substantially as is shown at 4, and a securing member 5 is hingedly mounted at 6.. that it will swing within the opening foamed by cnttii-iig away the mambo! 1. This securing Lateral-er is ofiset as :ndicstetl at 2" and the member 53 hes the en 8 of the bud thereof ffil'lk'led to abut against this effect at 'i, when the parts are brought to the reintion shown in Fig. 2, in such a Way thui; the end of the secur'm J member 5 lies against the inner sicle of the 0d of the member 2. A. locking memhoi 4, which is made snhstem tiaily in the for] of a turn button, is mount ed upon the mei'nber 2 and is so disposed that it can be turned to engage over the end of the secur ng member 5 and to fin d? h f. the same gmnm movement from that no: tie i. which it. been: against the inner sine of the member With parts: arranged as is above set forth, ohm it is desired to iii; the run withine casing i hie'i': is to be mounted thereon. the memlwr ie to have the free end hesrvof u ithin the member 3.. and-this nnemher i s .Ziitczl to the casing following the mem er 2 i= swung out and the securing; mezuhc 5 2?. moved, up to bring the 058% T thereof figle ns. the end 8 of the member it, following which the securing member is pried or forced up to rest against the inner side of the member 2 and to carry the free end of this member up to the proper Mined. relation w th reepect to the from and of the member .5 fo -towing which the hacking meme be!" ii turned. to engage we! the and 0t the securing member 5 and the parts are thus locked and secured. in the assembled relation. The bindin force of the tire against the rim portion wilof course act to hold the sections 1 and 2 of the rim against spreading outwardly, and when it is desired to again remove the casing, a hammer or other suitable instrument is used to turn the locking member 9 to disengage the same from the securing member 5, following which this member 5 is pried down to move the same from the bearing engagement against the inner side of the member 2, which operation causes the member 2 to be carried and swung therewith so that the abutting ends of the two members are disalined. When the locking and securing parts have been released, it wi of course be understood that the member 2 can be then swung to be disengaged from the casing, and then the member 1 can be readily lifted from its fitted position'within the casing.

To provide for holding and securing the rim in place upon the wheel. bolts 10 are passed through the telly to have their screwthreaded ends extended, the nuts 11 being mounted on the screw threaded ends. It is preferable that the threads of the bolts 10 and the nuts 1.1 be made of a reasonably steep pitch, for reasons which will be better hereinafter set forth, and the nuts 11 have extensions 12 at one side thereof shaped on their inner faces to conform substantially to the side ed e of the rim. In some instances it may be ound desirable to provide spaces within the folly in'which the nuts 11 are to work, and this is done by cutting out the same, this recess forming a socket for the reception of a locking washer 13, or other suitable means by which the nuts 11 will be held against casual turning or loosening on the bolts. Where the parts are fitted as is shown in Fig. 1, and the nuts 11 are turned to such position that the extensions 12 thereof rest against and secure the rim structure in place, the rim can be removed by giving each of the nuts 1.1 a half turn so that they will be loosed upon the bolts 10, and at the same time the extensions 12 will be readjusted to such position that they clear the rim member, and thus the rim, having a tire thereon, can be removed. When the rim. is

to be again secured in place, after having been fitted upon the wheel, the nuts 11 are turned in a direction to tighten the same, and when a half turn of these nuts has been accomplished, are brought to such relas tions that the extensions 12 thereof overlie and bear against the rim sections 1 and 2, in which relation the rim portion as an entirety is secured and substantially clamped in place upon the wheel felly. From the foregoing it will be seen that I have rovided a demountable rim structure which is of such character that it can be readily fitted to and removed from a casing, and when brought to the fitted position will have the ends thereof lockedand forcibly secured together; and also, it will be noted that a very efficient fastening is provided to hold the rim in place upon a Wheel.

While I have herein shown and described only certain specific forms and arrangements of the parts, it will be appreciated that changes and variations may be resorted to, in view of which fact I wish to be limited to only such points as may be set forth in the claim.

I claim A demountable rim including a pair of rim members hingedly connected together and so shaped that when fitted to a casing the ends thereof will be brought to an abutting relation, one of said rim members being cut out in the body portion at the free end, and a securing member having an offset therein mounted within the opening formed by cuttii'ig out the rim member and so shaped that when the free end of the remaining rim member is caught Within the oli'set thereof and this securing member is swung to be received in the cut out of the first mentioned rim member and lie ,in line with the body thereof the end of the rim member caught by the offset will be lined up and brought into an abutting relation With the rim member having the securing men'iber carried thereby.

In testimony whereof I ailix my signature in presence of two witnesses.
